` c'oNPosrrroN ROAD-BED.

, and chea-penedv construction of reinforced concrete bed' provided withcavities or depressions to receive the rail-supporting devices and alsoa centrally disposed trough for the reception of water.

It has fora further objectA to provide a concrete base upon which therail chairs or lfastening devices are supported.l

Other objects and advantages. of the invention will' hereinafter appearand the novel' features thereof will be particularly l pointed out inthe appended claims.

The invention is clearly illustrated in the accompanying drawings,which, -with the numerals of reference marked thereomform a' part of'this specification, and in which- Figure 1 is a perspective view of theinvention with parts in section and portions broken away showing animproved road bed and rails-mounted thereon. Fig. 2 is a verticaltransverse section through Fig. 1. Fig.

A3 is a perspective view of one of the chair supporting bases. Fig. 4 isa perspective view of one of the base-supporting springs. Like numeralsof reference indicate like parts throughout the several views. Incarrying out my invention, I form a base 1 of cement or analogousmaterial suit-- ably reinforced by meta-l reinforcing members 2, as seenin Figs. 1 and 2. The roadbed 1 is formed with cavities or chambers ordepressions 3, above which the rails are (le-- signed to be supported,and with an intermediate portion 4 for the reception of water for theusual purpose.

5 are the rails. These are supported upon the rail-supporting bases 6which are formed of cement or analogous material having the roughened orserrated portions 7 near each end upon the upper face, the intermediateportion being preferably left smooth, as shown at 8. Through each of theSpecification of Letters Patent.

serrated portions is formed a'vertical openmg 9 for the reception of thebolts, as seen in Fig. 3. This rail-supporting base has the central bodyportion 10 which is designed to lit quite snugly within the recess orchamber 3 in the roadbed, as. seen. in Fig, 2, leaving the surroundinghorizontal fla-nge 11, as Seen in Figs. l, 2 and 3, whichoverlap's theup- -per faceof the roadbed, as seen `in Figs.

l2l 1s' a spring of preferably the form shown in'Fig. 4. It has its-ends curled upwardly, as seen at 13, and its top portion is providedwith openings 14 for the passage of the bolts.

In practice, the springs are placed within` the chambers or cavities 3in the roadbed, as

seen in Figs. 1 and 2, the bolts 15 having been first disposed-withtheir heads 16 embedded in the cement or similar material of which thebase is formed, as seen clearly in Fig., 2, the openings 14 in the'upperportion of thespring being slipped over the bolts. Therail-'supporting base 6 is then placed in position, the boltsdpassing.through the openings 9 thereofan the body portion of'therail-sup orting base rests upon the sprlngf The rai -fastening devices17 are then applied over the bolts and the nuts 18 applied afterproperly adjusting the fastening de- As will lbe seen in Fig. 2,' thefastening devices 17 are provided with clon'- gated slots 19 so as topermit of proper adjustment of the rail-fastening devices. Therail-fastening devices areA serrated or roughened on their undersurfaces, as shown at 20,

for coperation with the .roughenedor serrated surfaces 7 of the rail-suY porting base 6. 'The springs 12 are of suc tension as to normally holdthe rail-supporting bases with their flanges 11 somewhat above the upperface of the roadbed, as seen in Fig. 2, so as to permit of the necessaryelastlcity and yielding when the weight of the train is upon the rails,the springs returning the s upporting-bases to thelr normal ositionsafter the train has passed. The un er face of the fiange 11 coming incontact with the upper face of the roa-dbed serves to limit the down-'ward movement of the rail-supporting base and the. ends of the springwill contact with` the adjacent walls ofthe chamber 3 to limit thedownward movement of the spring.
